[GRASS-dev] G__getenv return different results from ctypes and from GRASS modules

[Pietro]

Hi all,

Nikos A. found a strange behaviour... that I'm not able to understand...

I'm in the North Carolina (PERMANENT):

{{{
In [1]: import grass.lib.gis as libgis  # import the ctypes

In [2]: !g.mapset -p  # look in which mapset we are
PERMANENT

In [3]: libgis.G__getenv('MAPSET')  # look in which mapset we are using ctypes
Out[3]: 'PERMANENT'

In [4]: !g.mapset user1   # change the mapset
Your shell continues to use the history for the old mapset
You can switch the history by commands:
history -w; history -r /data/gis/nc/user1/.bash_history;
HISTFILE=/data/gis/nc/user1/.bash_history

In [5]: !g.mapset -p  # look in which mapset we are
user1

In [6]: libgis.G__getenv('MAPSET')  # look in which mapset we are using ctypes
Out[6]: 'PERMANENT'

In [7]: !g.gisenv
MAPSET=user1
GISDBASE=/data/gis
LOCATION_NAME=nc
GUI=text
GISDBASEE=/data/gis

}}}

Why the ctypes version return 'PERMANENT' instead of 'user1'?

the flag "p" of the module g.mapset use exactly the same function.

There is someone that is able to understand what is not working?
Any idea?

Best regards.
